Multi-channel Oxygen Meter for Parallel Monitoring with Multiple Sensors

OXY-4 mini

The OXY-4 mini is a multi-channel fiber optic oxygen meter for simultaneous read-out of up to 4 oxygen sensors. It is used with sensors based on a 2 mm optical fiber. A PC is connected to run the user-friendly software. OXY-4 mini is compatible with sensors type PSt3 (detection limit 15 ppb, 0 – 100 % oxygen).

  • For use with sensor spots (contactless measurement) & sensor probes
  • One calibration for a multitude of sensor spots
  • Software included

Applications

Food & Beverage: Oxygen Permeation Measurement in PET Bottles

Non-invasive oxygen sensors measure both in liquid and in gaseous (headspace) phases. They perform through transparent materials up to a thickness of 10 mm and even through slightly opaque packaging. The measurement is carried out by firmly holding the fiber optic probe against the side of a PET bottle where the sensor spot is positioned. Adjustable mountings and bespoke fixtures are available. This system allows even the parallel measurement of different bottles as the fiber can be moved from bottle to bottle.


Long-term Measurements in Soil

PreSens offers dipping probes for oxygen measurement that does not consume oxygen. Due to their small dimensions they do not disturb the flow and mass-transport and consequently display the in-situ oxygen concentration. As minisensors from PreSens are long-term stable they can be implanted in soil for many years! With this new method the process of soil aeration, which is very critical for plant productivity, can be investigated.
